PATENT JOSIAH H. MOORE, OF MONMOUTH, ILLINOIS, ASSIGNOR TO HIMSELF AND VILLIAM S. \VEIR, OF SAME PLACE.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 368,158, dated August 9, 1887. Application filed April 16. 1887. Serial No. 235,120. (No model.)

To all whom it may concern.-

Be it known that I, JOSIAH H. MooRE', residing at Monmouth, in the county of \Varren and State of lllinois,and a citizen ofthe United States, have invented a new and useful Improvementiu Cultivators, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is a perspective view showing so much of a complete machine as is necessary to illustrate the invention, and showing, also, the relation of the parts with the beam elevated. Fig. 2 is a perspective view similar to Fig. 1, with the spindle and wheel omitted, showing the relation of the parts with the beam down.

This invention relates to springs connected with the beam and the arch of a cultivator for the purpose of assisting the operator in elevating the beam, and which, when the beam is down, tend to hold the shovels to their work, and has for its objects to construct and apply a spring which will be effectual and reliable in use, and which can be readily applied to the beam and arch of a cultivator, and which is very simple in construction and operation; and its nature consists in providing a flat spring connected at one end to the cultivatorbeam and at the other end to a pivoted or swinging support attached to the arch, and in the several parts and combinations of parts hereinafter described, and pointed out in the claims as new.

In the drawings, A represents the swinging support or arm havingat its outer end asocket or car, a, and at its inner end a socket or car, a,and having an extension, projecting from its inner end and terminatingin a hook, (L in the form of construction shown.

B is a bracket or arm 011 which the arm or support A is mounted,byinserting therounded end b of the bracket B in the socket or car a of the arm. The bracket B,.as shown, is attached to the arch by a stirrup, b, the body of which encircles the vertical portion of the arch, and the ends of which pass through holes or slots in the bracket,and have nuts thereon, by which the adj ustmentis made secure. This manner of attaching is a simple one for either a round or square arch in crosssection; but the bracket can be attached in any other suit able manner.

C is a swivel having on each side ears 0, be tween which is located the outer end of the arm or support A, which end is secured between the cars by a bolt, 0, passing through the ears 0 and socket or car a, in the form of construction shown. The swivel G has a round tenon, c, which forms a pivot on which the swivel turns.

D is a ilat spring made of steel or othersuit- 6o able material, the forward end of which is connected with theswivel O by the tenon or pivot c, and the rear end of which is connected to the beam by two bolts, (1 d, in the form of construction shown, one of which, (Z, has a broad head with a slot therein, through which the body of the spring D passes, and by which the spring is held securely against side movement in the operation of the device. The swivel 0 forms a connection between the arm A and spring D, by which any slight variation between the arch and spring out of a straight line is compensated for and the spring maintained in a proper relation with the arm and beam to perform its work.

E is the plow-beam, of the usual and wellknown form of construction, and which is to be connected at its front end to the arch or other support, so as to be free to rise and fall and to turn to the right or left. The connec tion of the forward end of the beam can be made by the devices shown, which form asimple connection, and, as shown, F F represent plates, respectively, on the upper and lower side of the beam, and project forward of the beam end.

G is apivoted block having holes for the passage of the vertical bolt through the plates F F and the block, which bolt forms a pivot for the side swing of the beam, and the vertical swing is provided for by the block G.

H is a depending bar, through the rear end of which a bolt for pivoting the block passes.

I is the arch, formed of an upper horizontal and a vertical portion at each end, one end 5 only being shown, and to the vertical portion of the arch is attached the bracket or support B, which bracket can be made adjustable on the arch to adjust the relation between the arm A and spring D to give the spring D the proper tension.

The operation is as follows: The bracket or arm B is adj nsted on the arch for the proper tension of the spring, which is connected with the arm A by the swivel 0, so that the spring and arm will coact in the operation of raising andlowering the beam. The beam, when down, brings the spring D and the arm A into the position shown in Fig. 2, in which position the arm has passed its center and forms a resist-- ance against the spring, by which the spring is held inoperative so far as exerting a lifting force is concerned, and is made to exert a force against upward movement of the beam, and thereby acts to hold the beam down to its work; but when the beam and its shovels are to be raised the operator is assisted in the raising movement by the spring D and arm A,for the reason that as the beam is raised the forward end of the spring is advanced, carrying with it the outer end of the arm A, and as the arm is carried past its center in the forward movement the spring is left free to exert a lifting force, by which the beam is elevated. The beam, when elevated, in the construction shown, is held in its elevated position, so as to take the strain from off the spring and arm A by the hook a over which the spring is thrown; but the beam can be held in its elevated position by a hook extending out from the arch side bar or from the bar H, in the usual manner.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, with the plow-beam, of a spring, D, attached to the beam at its rear end, an arm or support, A, carried by the arch, and a connection between the arm A and spring 1), substantially as and for the purpose specified.

2. The arm A, bracket B, and swivel O, in combination with the spring Dand the plowbeam, substantially as and'for the purpose specified.
